Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Sponge Drops

Oven, in the book's wordsA very quick oven

Ingredients

Directions

The book says “a very quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Grease baking sheets with butter.

Make the batter

  1. Beat the eggs and sugar until frothy.

  2. Stir in the flour, cream of tartar, and baking soda.

  3. Add lemon flavoring to taste.

Bake and serve

  1. Drop teaspoonfuls of the batter about 3 inches apart on the sheets.

  2. Bake immediately in a 400°F (200°C) oven, watching closely to prevent burning.

  3. Serve with ice cream.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Beaten with sugar, they trap air that gives the drops their light, airy structure.
Sugar
Sweetens the drops and helps stabilize the beaten egg foam.
All-purpose flour
Provides the starch and gluten network that sets the drops into a firm, cakey structure.
Cream of tartar
Acidic, it reacts with baking soda to produce gas that makes the drops rise.
Baking soda
Releases carbon dioxide when combined with the acid, leavening the batter for lift.

The step that matters

Bake immediately after dropping the batter. Cream of tartar and baking soda start producing gas as soon as they are wet, so batter left standing loses rising power. Watching the oven closely matters because the small drops brown and burn quickly.

Swap the lemon

How well each one fits the dish's main ingredients (egg, sugar, flour, cream, butter):

  1. Vanillafits better
  2. Raisinfits better
  3. Coconutfits about as well
  4. Lemonthe original

Fit is the average pairing score against egg, sugar, flour, cream, butter. Candidates are from the same food group and used in at least 100 recipes.
